Made from flexible silicone, this squeezable baby bottle and nipple feeds more naturally. The soft, wide nipple mimics the shape and feel of the breast. It has an easily assembled design and a unique, leak-proof vented nipple, which reduces colic. BPA-free and approved for microwave, dishwasher and boiling water. Comotomo bottles are wide so they are easily cleaned with a regular sponge. No need for brushes! Comes in a 2-pack.
